This question appears to be off-topic because it is a bug report and not an actual question. These should be reported to Blender's tracker instead.
We usually close questions which were asked buggy behavior as bug reports, regardless of whether or not the question was not phrased as a bug report, or even of the OP seemed to realize there was a bug (related: When should a question be closed as a bug report?).
TL;DR: We get "actual questions" which should still be closed as bug reports, as they pertain to a bug (though often the OP isn't aware of this).
To reflect this, can we change the close reason to something like the following?
Not completely happy with this phrasing, perhaps someone will have a better idea...
